    Large File Support OEL 5.8 x86 64 bit




      I have downloaded some software from OTN and would like to combine the individual zip files into one large file. I assumed that I would unzip the individual files and then create a single zip file. However, my OEL zip utility fails with the file is too large error.


      Perhaps related, I can't ls the directories that contain huge files. For example, a huge VM image file.


      Do I need to rebuild the utilities to support huge files or do I need install/upgrade rpm's?  If I need to relink lint programs, what are the commands to do such?

          What file sizes are you talking about?


          The question typically isn't large file support in Oracle Linux (OL), but rather a question of the zip/unzip utility. UnZip's random-access operation and (partial) dependence on the stored compressed-size values limits the total size to something in the neighborhood of 2 to 4 GB.


          See the following link: http://www.info-zip.org/FAQ.html#limits


          OL ships with unzip version 5.52.


          if you want to archive zip files I suggest to use the tar utility, for instance: tar cvf myfile.tar *.zip

            Correction:  This is occurring on a 5.7 release and not a 5.8.  The command uname -a yields 2.6.32-


            The file size I'm trying to assemble is ~ 4 GB (the zip files for 12c DB).  As for using tar, as I understand it, EM 12c wants a single zip file for software deployments.


            I'm assuming that the large file support was not linked into the utilities. For example when I try to list contents of a directory which has huge/large files, I get the following message:


            ls:  V29653-01.iso:  Value too large for defined data type


            I'm assuming that I need to upgrade to later release.

              The kernel version does not necessarily explain the Linux release version. Are you sure you are using a x86_64 kernel? Large file support, from what I understand means 64-bit support. Perhaps you are using a 32-bit (i686) system.
